  • 본 연구는 충남 보령 학성리 갯벌 조간대에서 대형저서동물의 시·공간적 분포 및 군집구조를 파악하고, 환경요인에 따른 군집구조 변동을 알아보고자 하였다. 현장조사는 2016년-2017년에 계절별로 9개 정점에서 캔코어(13 cm × 22 cm × 30 cm)를 이용하여 각 정점마다 3회 반복 채취 수행하였다. 퇴적환경은 전반적으로 니질 함량이 60% 이상이었으며, 유기물 함량은 평균 2.3%이었다. 대형 저서동물은 총 79종이 출현하였고, 평균서식밀도는 611 ind./m2, 평균생물량은 64.1 gWWt/m2이었다. 상위 우점종은 니질 갯벌에 서식하는 고리버들갯지렁이(Heteromastus filiformis), 칠게(Macrophthalmus japonicus)와 쏙(Upogebia major)이며, 서식밀도는 각각 297 ind./m2(48.6%), 62 ind./m2(10.1%), 42 ind./m2(6.9%)으로 나타났다. 집괴분석으로 분류된 3개의 정점군은 물리·화학적인 환경요인 보다는 생물상호 작용과 우점종 출현비율 등으로 구분되었으며, nMDS 분석으로 살펴본 대형저서동물 군집은 계절적 변동양상을 보였다.

  • The Korea Water Resources Corporation(KOWACO) proposed bidding for an alternative design for Hwabuk Multi-purpose Dam in March of 2004. The site is located in Hakseong-ri, Goro-myeon, Gunwi-gun, Gyeongsangbuk-do and has adrainage area of $87.52km^2$. The purpose of this project is to establish an environmentally friendly plan for minimizing the damage that was caused by the construction of the Hwabuk Multi-purpose Dam. The design principle of KOWACO was the restoration of the natural environment, a harmonious landscape, and the creation of a space of regional and local culture. The basic concept of this project involves an ecological-restoration axis and a functional-connection axis. The site is divided into four spaces: (1) the space of memory and symbol, (2) the space of nature and ecology, (3) the space of regional and local culture, and (4) the space of the regional economy. There are four sub-spaces in the space of memory and symbol: the track forest, the time forest, the memory room, and the sun plaza. There are three sub-spaces in the space of nature and ecology: the habitat of aquatic birds, the wind forest, and the eco-corridor. There are five themed parks in the space of regional and local culture: the culture and relic room, the wildflower garden, the ecological pond, the insect observation park, and the pyogo maze. There are three areas in the space of the regional economy: the forest pension, the waterside pension, and the community center, as Dungdungi village was reorganized to serve as a lodging complex. These themed parks, working together, can offer an effective space for nature, culture, rest, and experience.
